COMBINED BENBING IvlirCHNE AND V Application led January 17, i922.

T o all whom t may concern.'

Be it known that I, CLARnNon S. GORDON, a citizen or" the United States,and resident ol Los Angeles, in the county of Los Angeles 5 and Stateot' California, have invented new .and useful Improvements inCombinedBending Machines and Vises, of which the following is aspeciiication.

This invention relates to bending machines, and more particularly to aform of bending machine and vise combined, wherein strips or pieces ofmetal of different sizes and shapes may be tightly held and bent to arequired angle in a simple operation and 16 in an effective manner.

The primary object of my invention is to provide a bending machine ofsimple design and with a minimum number Vot parts, so held together thatthey may be 20 readily assembled and disassembled and arranged' to besupported on a worlr bench or table, as in the case of ordinary benchvises.

An object of my invention is to provide in a machine of the charactermentioned, a

base adapted to be stationarily supported on a bench or table, and a.plurality of 'relatively adjustable forming blocks mounted on said baseand provided with jaws for gripping strips or pieces of metal, andadapted I0 for clamping the strips or pieces of metal rigidly inposition, one of said forming blocks being pivotally held Von said baseand adapted to be swung thereon for bend'- ing the metal against the jawof the other forming block. n

Another object is to provide in combination with a stationary basehaving a slidably adjustable forming block mounted thereon, anotherforming block pivotally and slidably mounted on said base, so that thejaws thereof may be disposed at any desiredangle with respect to the jawof said other forming block, for the purpose of holding strips orpiecesY of metal at any desired angle on the base, and capable of use asa vise when the movable forming Vblock is stationary held.

Still another object is to provide a stationary base having a screwoperated forming block slidably held thereon, and a swivel forming blockpivotally held thereon, and including relatively stationary and movablejaws forming a vise for gripping the strips or pieces of metal in abending operation, or for the purposes of an ordinary vise.

Serial No. 529,979.

@ther minor and detailed objects of invention will appear as thedescription progresses. Referring now to the annexed drawings, in whichl'liave shown a preferred embodinient of my invention, subject tomodification within the scope of the appended claims:

A5 shown in the drawings, B represents base which has a horizontal webl, one portion ofwhich is rectangular, as at Z), and the remainingportion semi-circular, as at 7). The portion o has a semi-circular rib 2extending above the surface of the web l, and the upper edge of said ribis adapted to be machined smooth for purposes hereinafter described.

The rectangular portion b of the base has a plurality of bores 3, 3,etc., formed therein and adapted t0 receive bolts 4, 4, for the purposeof holding the base stationarily on a table. or bench T. In theapproximate center of the base B, l provide a boss 5 which is concentricwith therib 2er the portion and is bored at 6 to receive a stud 7,

either integral with or iiXed to a corresponding boss 8 in the viseframe V, which is supported on the upper surface of the base B and isadapted to swing about the axis of the stud and over the upper smoothsurface. et the rib 2. V

The stud 7 may have a. reduced threaded portion 9 on the lower en dthereof, so that a nut 10 may be threaded thereon below the boss 5 ofthe base, for holding the vise frame in position on the base. The vise Vhas an integral jaw J on'the inner end thereof and extendingtransversely across the vise, so that when the vise is positioned asshown in 1, the inner surface 10 of the jaw J will be disposedtransversely ot the base B, The jaw J oli' the vise is preferably in twoportions, one of which is higher than the other, and the inner corner 11of the higher portion of said jaw is alined with the axis of the swivelstud 7 of the vise.

The vise V has an extension 12 of rectangular cross section whichisdisposed at right angles to the body of the vise and is recessed toreceive a bar H which constitutes a handle whereby the vise may be swungon its aXis Lover the rib 2 of the vise, and said vise also has anarcuate web 13 which connects the extension 12 and the vise body, andhas its outer edge formed substantially flush with the outer edge of therib 2 of the base and adapted to be moved over said rib, as shown inFigs. 1 and 2.

The extension 13 is provided with a hole 14 and the base B is providedwith a pair or more of holes 14 with which the hole 14 of extension 13is adapted to register, when the vise is positioned as shown in Fig. 1,or when extended to an acute angle relative to the base. The vise maythereafter be stationarily held on the base by inserting a bolt pinthrough the hole 14 and one of the holes 14 when the vise is to be usedfor ordinary purposes of such devices.

The vise body is provided with a longitudinal extension 15 ofrectangular form and the upper portion thereof has guides 16, 16 formedthereon with a guideway 17 therebetween, which is adapted to receiveali-orming block F of slightly narrower width than the extension 15 ofthe vise. Said forming block has a jaw J termed on the inner end thereofand corresponding to the jaw J of the vise bodv.v The inner ysurface 18of said jaw being parallel at all times with the sur- Vlace 10 of theyjaw J, so that the strip or piece of metal, as at W, may be heldtransversely in the vise betweenthe jaws J and J and clamped thereon bymeanshereinafter described.'

The jaw J is braced against the base 19 of the forming block F by meansof a rib 20 and a pair of spaced lugs 21, 21 are integrally formed ontbeblock F andnear the forward end thereof, and depend down? wardly througha central opening 22 in the vise trame V.

The lu s 21, 21, are bored at 22 to receive a screw which has a reducedportion 23 j ournaled in a hole 24 in the outer end 25 of the vise`iframe, and is additionally j ournaled in a bearing 26 beneath the jawJ or" said vise. Said screw has an extension 27 extending rearwardlyover and substantially beyond the rib 2 ot base B, and the rear end ofsaid extension has a handle It pivotally held thereon and capable ofextension to right angles with respect to the screw, so as to effect theturning of the screw in its bearings.

A nut N is threaded onto the screw S between the lugs 21, V21 of theblock F and has a central portion 28, which extends upwardly into arecess inthe base 19 of said block and lateral extensions 29, 29 withdiametrically alined surfaces 30, 30 thereon adapted to slidably engageguideways 31, 31, formed on the lower side of the vise frame V, as shownin Fig. 4.

Thus, it will be apparent that the turning of the screw S by means ofthe handle It will effect the corresponding movement of the nut Nlongitudinally of the vise trame, and

the nut N being held between the lugs 21, j

21, of the forming block F will correspondingly slide said blocklongitudinally on the vise frame V, so as to regulate the space betweenthe jaws J and J of the vise and forming block respectively, forclamping the work V between said jaws.

It will be understood by reference to Fig. 1 that the inner edges of thejaws J and J are at all times parallel and longitudinally disposed on aline cutting the axis of the base, preparatory to a bending operation,and when the vise is moved for effecting the complete right angle bend,the inner edges of said jaws will he alined transversely or" the base ona line cutting the axis thereof.

A guideway 32 is formed on the rectangular portion of the base B, withguides 33, 33, at ythe sides thereot` :For slidably receiving a formingblock F which is mounted on the upper surface of the base in a pla-neslightly below the level of the block F on the vise. It will be notedthat the blocks F and F have longitudinal recesses 32, 32, cut in thesides thereof and corresponding to the guideways 17 and 32 oithe viseand base respectively, in which said blocks are adapted to slide.

The forming block F has a jaw J1 on the inner end thereof and a grippingsurtace 34 which is adapted to be alined with the surface 18 ot theblock F, as shown in Fig. A1, and the inner edge of jaws J and J1 ofblocks F and F are adapted te he substantially in abutting position, thejaw J1 ot block F being braced against the base 35 of Said block bymeans of a rib 36,

Block F has depending lugs 87, 37, thereon which correspond to the lugs2l, 2l, of block F, and said lugs 37 are bored at 38 to receive a screwS corresponding in character to the screw S of the vise. The outer endof screw S is reduced at 39 and is journaled in the rib 40 of the base,while the portion 4l at the rib of said screw is jour naled in thetransverse rib 42 ot said base.

The screw S also has an extension 43 which exends rearwardly through anopening 44 in the web 1 of the base, and is journaled in a boss 45formed on said base, and is provided at its rear end with a. handle z.pivoted thereto and corresponding to the handle /z` on screw S. A nut Nsubstantially similar to the nut N of the vise, is threaded to receivethe screw S and is held between the lugs 37, 37 of the forming block F,so that when the screw S is turned the forming block F will be movedlongitudinally on the base to an extent corresponding to the movement ofthe block F on the vise. The nut N has the lateral portions 29, 29 whichengage guideways 46, 46 formed on the body of the base, as shown in Fig.4, and serve to guide the nut in its movement thereover.

The ends 23 and 39 of the screws S and S are provided with cotter pins47, 47 for preventing the withdrawal ot the screws from their bearings.

Now, in operation the vise V is positioned with respect to the formingblock F and the base B, as sho-wn in Fig. l. The blocks F and F" areadjusted by means ot the screws S and S respectively, so as to be alinedtransversely of the base and in spaced relation to the jaw J of thevise, the work lV which is to be bent is then placed in position by thejaws J and J of the vise and against the jaw J1 of the block F,whereupon 'the screws S and S are turned vfor tightly gripping the workbetween the adjacent surface of the jaws. Thereafter the vise V may beswung in a clock-wise direction on the base and over the rib 2 thereofby means of the handle H, to any extent up to and including a rightangle for the 'torni ot' device shown in the drawings. ln lsuch case theportion of the work W which gripped between the jaws J and J will bebent at an angle relative to the portion which abuts the jaw Jl,thereafter the screws S and S may be turned for looseningl and removingthe work l from the vise.

lt will be understood in this connection that the jaws oit the formingblocks may be so formed and the machine so devised as to permit theturning of the vise on the base so to make bends of greater extent than90 degrees, `but in the drawings l have shown device arranged only formaking bends up to and including 90 degrees.

When the work is removed from the vise, the vise may be restored tonormal position and other strips or pieces of metal insertedsuccessively tor other operations, and said operations are performed ina like manner.

In the event that the machine isto be used for ordinary purposes of avise, the screw S may be operated for removing the block F, so as toclear the Work, and the work may be gripped between the jaws J an J otthe vise proper. ln such case, a bolt or pin may be inserted through theholes 14 and 14 or" the vise and base respectively7 `for holding thevise immovable on the base while the vise is being so used.

It will be observed that the vise may be turned to an acute angle on thebase so as to be more convenient and accessible for the reception ofcertain kinds of work, and to better clear the forming block F.
